为了安全起见,服务器的ssh端口从默认的22修改为了22222
在安装RAC时,oracle用户间做了互信,但是并不能通过ssh直接连接,必须要加上-p 22222才能
这就会导致在安装crs时验证不通过,表现为:
Caught Cluster ExceptionPRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh
tgdb1: Connection refused
[PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh
tgdb1: Connection refused]
[PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh
tgdb1: Connection refused
[PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh
tgdb1: Connection refused]]
看来oracle是直接调用的ssh命令,并不会加上-p 22222,这就导致了节点间不能通信的假象
解决办法:
修改/etc/service
把其中ssh 22222/tcp # SSH Remote Login Protocol
的端口修改为22222解决
